AI Technical Summary

Benefits of technology

The present invention is a webbing take-up device that prevents or suppresses an increase in size of a member that anchors a base end of a coupling member, such as a cable, that operates an acceleration sensor. The device allows for adjustment of the initial position of the housing of the acceleration sensor with respect to the moving body without changing the anchoring position of the coupling member. This results in a reduction of size of the moving body and prevents or suppresses an increase in size of the member that anchors the base end of the coupling member.

Problems solved by technology

However, in such a configuration, shift of the position of the join between pinion meshing side and the cable other end retaining side results in an increase the rack dimension in the length direction thereof.

first modified example

[0118

[0119]In the present exemplary embodiment, the bent portion 400 and the spring-side step portion 402 are only formed at the spring 392 length direction one end side, however for example as shown in the first modified example in FIG. 12, the bent portions 400 and the spring-side step portions 402 may be formed at both length direction end sides of the spring 392, and mounting portion-side step portions 404 may be formed to the inner walls of the retaining spring mounting hole 258 corresponding to the spring-side step portions 402 on both sides.

[0120]In the present exemplary embodiment, configuration is made wherein the metal cylinder body 256, and therefore also the base end of the tube 254, are retained indirectly to the case 212 due to friction between the spring-side step portion 402 and the mounting portion-side step portion 404 caused by the resilient press contact of the spring-side step portion 402 of the spring 392 against the mounting portion-side step portion 404 of th...

second modified example

[0121

[0122]FIG. 13 and FIG. 14 are drawings corresponding to FIG. 5 and FIG. 6 and show a second modified example of the present exemplary embodiment. As shown in FIG. 13 and FIG. 14, in this modified example, a male thread portion 452 configuring a retention section is formed at an outer peripheral portion of the metal cylinder body 256. A female thread hole 454 serving as a female thread portion, so as to correspond to the male thread portion 452, that configures the retention section together with the male thread portion 452 is formed in place of the retaining spring mounting hole 258 of the case 212.

[0123]A one end of the female thread hole 454 is open at an outer peripheral portion of the case 212, and the other end is in communication with the inside of the case 212 through the notch portion 260. A female thread is formed to at least a portion of an inner peripheral portion of the female thread hole 454 between the one end and the other end of the female thread hole 454. The m...

third modified example

[0125

[0126]FIG. 15 and FIG. 16 are cross-sections corresponding to FIG. 5 and FIG. 6 and show a third modified example of the present exemplary embodiment. As shown in FIG. 15 and FIG. 16, in this modified example, the case 212 is not formed with the retaining spring mounting hole 258 having the mounting portion-side step portion 404, but is instead formed with an interference block mounting hole 460. An interference block 462, formed from for example a rubber material or synthetic resin material having a similar resilience (elastic) to rubber, is mounted in the interference block mounting hole 460.

[0127]The inner peripheral shape of the interference block 462 is formed as a cylinder shape with it being larger than the outer peripheral shape of the metal cylinder body 256. In the inner peripheral portion of the interference block 462, with specific intervals along the metal cylinder body 256 axial direction, plural resilient (elastic) interference portions 464 that configure the ret...

Abstract

A length direction base end side of a wire passes through a retaining spring mounting hole formed in a case, and is anchored to an anchor tag that is indirectly retained by a pulley. A spring is provided in the retaining spring mounting hole, and a base end of a tube is retained to the spring through a metal cylinder body. A spring-side step portion of the spring is pressed contact to a mounting portion-side step portion of the retaining spring mounting hole so the spring is retained. When the tube is pulled towards an opening side of the retaining spring mounting hole, the spring moves and the spring-side step portion makes press contact with, and is once again retained, by a different step of the mounting portion-side step portion.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 USC 119 from Japanese Patent Application No. 2012-025402 filed Feb. 8, 2012, the disclosure of which is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a webbing take-up device configuring a vehicle seat belt device.[0004]2. Related Art[0005]Japanese Patent No. 3767197 (Patent document) discloses a webbing take-up device (referred to as a seat belt retractor in the Patent document) provided inside a seat back of a vehicle seat that has what is referred to as a reclining mechanism. The webbing take-up device is provided with an acceleration sensor for actuating a locking mechanism when the vehicle decelerates suddenly, and a sensor case of the acceleration sensor is provided to be capable of turning with respect to a frame or the like of the webbing take-up device.[0006]One end of a cable is anchored to the sensor case...
